17.l j This Wedge is threaded at 18 fory the reand is thus provided with arms 39 and 40. A yoke 4l is provided, having a head 42 and tapered legs 43 and 44. The legs 43 and 44 are slid between the arms 39 and 40 and the lug 37, which lug is provided along the longitudinal extremities of both surfaces with upstanding fianges 45. By means of one orl more bolts 46, the yoke 41 is firmly wedged against the tapered arms 39 and 40 of the forked brake beam 36. In this manner, the brake-shoe head is firmly secured in position and at this time lock bolts 47 which extend through the brake beam, yoke, legs and lug 37 may be tightened to hold the elements in their assembled relation.

As will be readily understood, the invention is susceptible to numerous modifications, and it is intended that it be limited only by the scope of the appended claims.

I claim:

1. In combination, a brake-shoe head having a. rearwardly-extending portion, a brake beam, a wedge-shaped means for securing rsaid rearwardly-extending portion to said brake beam, adjusting means for said wedgesha ed means and means for securing said brake beam, said wedge-shaped means, and said rearwardly-extending means in their assembled position. y

2. In combination, a brake-shoe head having a rearwardly-extending portion in which there is a taperedopening, a brake beam extending through said opening, wedge-shaped means extendlng through said opening and adjusting means for causing said wedgeshap'ed means to secure the brake-shoe head against said brake beam, and means extendin through said head, said brake beam and said wedge to fix them in their assembled position. f
